#Prerequisites

This assumes basic development environment setup (git, directory structure). Please follow the "New Developers Tutorial" for basic steps.

Pyon: The main dependency of this repository is the pyon Capability Container. Follow the listed steps to install the minimal needed dependencies to run pyon on a Mac. For more details and Linux install instructions, check out the pyon README: https://github.com/ooici/pyon/blob/master/README

Install the following if not yet present:

• git 1.7.7: Download the Mac or Linux installer and run it

• OS Packages and package management: For Mac, use homebrew

  /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

• python 2.7 see below for installation

• couchdb 1.1.0 (optional if memory mockdb is used) see below for installation

• rabbitmq 2.6.1 or later (recommended, but can use rabbitmq on amoeba) Download generic Linux version and unpack into a suitable directory. Note: May need erl (Erlang) and some dependencies installed before

• Install libevent, libyaml, zeromq, couchdb, python, and rabbitmq with Homebrew

  brew install libevent libyaml zeromq couchdb python rabbitmq

  You can even reinstall git using brew to clean up your /usr/local directory Be sure to read the pyon README for platform specific guidance to installing dependent libraries and packages. Linux: Note that many installs have much older versions installed by default. You will need to upgrade couchdb to at least 1.1.0.

Python packages and environment management:

• pip

  easy_install pip

• virtualenv and virtualenvwrapper modules for your python 2.7 installation

  easy_install --upgrade virtualenv easy_install --upgrade virtualenvwrapper Note: This may require Mac's XCode (use XCode 3.3 free version)

• Setup a virtualenv to run COI-services (use any name you like):

  mkvirtualenv --no-site-packages --python=python2.7 eoi Note: Do not use the pyon virtualenv if you are a pyon developer

###Compiled Library Dependencies hdf5 library

brew install hdf5

netcdf

brew install netcdf

###Python Dependencies numpy

pip install numpy

matplotlib

pip install -e git+https://github.com/matplotlib/matplotlib#egg=matplotlib-dev

###Other OOI-CI Project Dependencies

This project requires that both the pyon and eoi-services projects are installed in the same directory as the pydap-handlers-ion project (typically the "Dev/code" directory if the OOI-CI development directory structure is used). These projects can be obtained using the following commands:

git clone git@github.com:ooici-eoi/eoi-services.git
git clone git@github.com:ooici/pyon.git

#Source

Obtain the eoi-agents project by running:

git clone git@github.com:ooici-eoi/pydap-handler-ion.git
cd pydap-handler-ion

#Buildout

Build the project using buildout

python bootstrap.py
bin/buildout

#Running the test server

You can test the ION handler for pydap by starting the test server

bin/run-server.sh

Then browse to http://127.0.0.1:8001 to see and interact with the test datasets
